User reviews

Tags list don’t scroll

With updates , Tags list with many tags don’t scroll. That way the save button is not reachable.
Please fix that bug.

The notes don’t work!

After the recent update the adding of the notes/ tags after you set the alarm don’t work. The icons are too big to “submit” or whatever it was and if you swipe down it goes away. Fix this.

Update made it worse

This latest update has made the app harder to use. The notes that you can add to large but you can’t scroll or save them. The brightness is much too bright. Please adjust.

Why log in?

Been using this alarm app for nearly 15 years. Why do you need an account to use it now? Why is there no guest option? I just want to set my alarm. This is heartbreaking. I knew something was in the works when the ads change about a month ago. Sad

Screen too bright since latest upgrade

I’ve used Sleep Time for well over a decade and have genuinely loved it. That’s why this latest update is disappointing. The new interface has too many bright white buttons and screen elements, making it much too bright for nighttime use. For a sleep app, dark, low-light usability should be a priority. Please consider adding a true dark mode or reducing the brightness of the buttons. I’d love to keep using the app I’ve trusted for years.
